Department of Transportation March 11, 2005 – Federal Register Recent Federal Regulation Documents

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 727 airplanes. That AD currently requires repetitive detailed inspections to detect cracking, corrosion, and existing stop-drilled repairs of cracking in the upper chord of the rear spar of the wing; and repair if necessary. This new AD requires new repetitive inspections to detect cracks, corrosion, minor surface defects, and existing stop-drilled repairs of cracks in the upper and lower chords of the front and rear spars of the wing; and repair if necessary. This AD is prompted by our determination that further rulemaking action is necessary to require additional actions specified in the referenced service bulletin. We are issuing this AD to prevent structural failure of the wing and fuel leaks in the airplane due to stress corrosion cracking of the wing spar chords.

This document corrects a typographical error that appeared in airworthiness directive (AD) 2005-03-12 that was published in the Federal Register on February 14, 2005 (70 FR 7386). The typographical error resulted in an incorrect AD number. This AD is applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes. This AD requires initial and repetitive inspections of certain frame stiffeners to detect cracking and replacement of any cracked stiffener with a new, reinforced stiffener. Replacement of the stiffener constitutes terminating action for certain inspections. This AD also requires a one-time inspection of any new, reinforced stiffener; and repair or replacement of the new, reinforced stiffener if any cracking is found during the one-time inspection. This AD also provides for an optional terminating action for certain requirements of this AD.

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action revises Class E airspace at Point Lay, AK to provide adequate controlled airspace to contain aircraft executing three new Standard Instrument Approach Procedures (SIAPs). This Rule results in new Class E airspace upward from 1,200 feet (ft.) above the surface at Point Lay, AK.

This action establishes Class E airspace at Beluga, AK to provide adequate controlled airspace to contain aircraft executing Special Instrument Approach Procedures. This Rule results in new Class E airspace upward from 700 feet (ft.) above the surface at Beluga Airport, AK.

The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires repetitive detailed inspections of the aft fuselage frames for any discrepancies, and any applicable corrective actions. This AD is prompted by reports of corrosion found on the aft fuselage frames due to the ingress of water or liquid. We are issuing this AD to detect and correct corrosion of the aft fuselage frames, which could result in reduced structural integrity of the fuselage.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing transport category airplanes. This AD requires repetitive detailed inspections to detect cracking of the aft and forward surfaces of the bulkhead web at nacelle station 180, and repair if necessary. This AD is prompted by reports of cracking of the web bulkhead at nacelle station 180. We are issuing this AD to detect and correct fatigue cracking of the web bulkhead, and consequent loss of the load path of the bulkhead at nacelle station 180, which when combined with the loss of the midspar load path, could result in the in-flight separation of the engine and strut. Such separation may result in secondary damage to the airplane and consequent reduced controllability of the airplane.

This notice proposes to establish Class D airspace at Front Range Airport, Denver, Co. An Airport Traffic Control Tower (ATCT) is being constructed at Front Range Airport, Denver, CO which will meet criteria for Class D airspace, Class D airspace is required when the ATCT is open, and to contain and protect Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action would establish Class D airspace extending upward from the surface to 8,000 feet Mean Sea Level (MSL) within a 5.1 nautical mile radius of the airport.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes; equipped with certain Honeywell inertial reference units (IRUs). This AD requires revising the Limitations section of the airplane flight manual to prohibit the use of CAT 2 and CAT 3 automatic landing and rollout procedures at certain airports. This AD is prompted by a report that some magnetic deviation tables in the IRU database are obsolete and contain significant differences with the real magnetic deviations. We are issuing this AD to prevent an airplane from deviating from the runway centerline, and possibly departing the runway.
